1 PVAAS Overview: Evaluating Growth, Projecting Performance PVAAS Statewide Core Team for PDE Fall 2012 1

2 Partners & Teams for Session Activities Some activities throughout the session will be completed in pairs or small groups, while others will be done independently. Take a few minutes now to divide yourselves into: Partners (groups of 2), AND Small groups (groups of 4-6). Fall 2012 2

3 Session Workbook Workbook contains: Key notes from PowerPoint Session activities Yellow boxes on PPT slides indicate the page number(s) you should be referencing in your workbook. Fall 2012 3

4 Goal of Session By the end of the session, participants will be able to answer the following questions: What is PVAAS? What does PVAAS tell us about how students are projected to perform on a future PSSA? How does PVAAS measure growth? What does PVAAS tell us about growth in our district and school(s)? Which reports are most meaningful for school level planning, grade level planning, and student level planning? WB P. 1 Fall 2012 4

5 What Is PVAAS? Fall 20125

6 PVAAS: Is an analysis of existing assessment data Longitudinal PSSA scores in available content areas of Math, Reading, Science, and Writing Provides reliable projections and estimates of growth Is a measure of district’s and school’s effectiveness and growth over time Provides information on the critical relationship of… Growth vs. Achievement WB P. 2 Fall 2012 6

7 PVAAS: Is not another test Is not a comparison of single test scores! WB P. 2 Fall 2012 7

8 In the Perfect World… Calculating Growth Measures would be easy The 3 M’s would not exist Measurement Error Mobility Missing Data We live in the real world! Fall 2012 8 WB P. 3

9 PVAAS Analyses Address the Issues – the 3 M’s! How? Research-based Statistical Modeling Minimizes the effects of measurement error associated with any one test score Measurement Error Accounts for mobility of students Mobility Compensates for missing data Missing Data Fall 2012 9 WB P. 3

10 PVAAS uses advanced statistical methodologies   Multivariate Response Modeling (also known as the Growth Standard Methodology)   Univariate Response Modeling (also known as the Predictive Methodology) Research-based Statistical Modeling Regularly used in other fields, such as psychology, pharmaceutical sciences, health care, and medicine Proven to be precise and reliable Fall 2012 10 WB P. 3

11 Achievement vs. Progress Student Achievement: Where are we? Highly correlated with demographic factors Student Progress: How far have we come? Highly dependent on what happens as a result of schooling rather than on demographic factors By concentrating on the progress students make, PVAAS puts the emphasis on something educators can influence! Fall 2012 11 WB P. 4

12 Demographics and Growth As long as you can sufficiently account for the prior achievement of the student,… WB P. 4 Fall 2012 12 …there is NO significant relationship between demographics and student progress, or growth!

13 Prior Achievement How can we adequately account for prior achievement? What about measurement error in test scores? The SAS, Inc. EVAAS team has found, the only way to adequately account for prior achievement is to use all available test data for each student to dampen the effects of measurement error. WB P. 4 Fall 2012 13

14 In Summary… Is there a relationship between: Demographics vs. Achievement? YES Demographics vs. Growth? NO WB P. 4 Fall 2012 14 PVAAS does not need to adjust for the demographic status of students directly since it is accounting for the students’ prior achievement. In other words, demographics are inherently controlled for in PVAAS by the use of all longitudinal data on all students.

15 Summary and Reflections Work with a partner to complete the activity on page 5 of your workbook. WB P. 5 Fall 2012 15

16 Summary and Reflections Answers WB P. 5 Fall 2012 16

17 Two Types of PVAAS Information Fall 201217

18 PVAAS Analyses PSSA Writing PSSA Science PSSA Reading PSSA Math LOOKING AHEAD Planning for Students’ Needs: Student Projections to Future Tests LOOKING BACK Evaluating Schooling Effectiveness: Value Added & Diagnostic Reports 18 Keystones WB P. 6 TWO Types of PVAAS Information Fall 2012

19 PVAAS Projections Individual Students and Groups of Students Fall 201219

20 How Are Projections Used? 20 Weather Forecasts Population Growth Demand for Electricity Inventory Management Investment Strategies Fall 2012

21 What Are Projections? Given a specific set of circumstances… …what’s the most likely outcome? WB P. 6 Fall 2012 21

22 Setting Expectations How do teachers set expectations for their students? Information o o What do they know about this student? Experience o o How have students like this one performed in the past? 22 Fall 2012 WB P. 6

23 PVAAS Projections What are they based on? Expectations based on what we know: o o About this student » » Prior test scores (PSSA), across subjects o o About other students who have already taken this test (PSSA) » » Their prior test scores (PSSA), across subjects » » Their scores on the test (PSSA) to which we are projecting o o About how much progress students at this school have made in the past in this subject, on average » » Growth Measure from School Value-Added Report 23 Fall 2012 WB P. 6

24 Given this student’s testing history, across subjects… …what is the student likely to score on an upcoming test, assuming the student has the kind of schooling experience this school has provided in the past? What Are PVAAS Projections? WB P. 6 Fall 2012 24

25 Student Projection Methodology What data are used in this methodology? ALL available longitudinal data in both Reading and Math are used in projection calculations for all subject areas. Science data are also used in projection calculations for Science. Likewise, Writing data are also used in projection calculations for Writing. What students have projections? In what subjects? Projections are available for all students who have a minimum of 2 years of historical data. The next slide details the grade levels and subjects in which projections are reported. Fall 2012 25 WB P. 7

26 PVAAS Reporting: Projections to PSSA (Basic, Proficient, Advanced) Grade PSSA Last Taken Math and Reading:  3  4 or 5  4  5 or 6  5  6 or 7  6  7 or 8  7  8  8  11 Writing:  3  5  4  5  5  8  6  8  7  8  8  11 Science:  3  4  4  NA  5  8  6  8  7  8  8  11 Grade PSSA Last Taken Grade PSSA Last Taken WB P. 7 Fall 201226 Projections to Keystone Exams available in fall 2013

30 PVAAS Projections for Groups of Students Student Search WB P. 11 Fall 2012 30

31 Identified Students Meeting Search Requirements WB P. 11 Fall 2012 31

32 Quality of Projections for Decision Making PVAAS projections have been reviewed and approved by four different peer review panels and the US Government Accountability Office prior to being used as one of Pennsylvania’s Provisions for making AYP. Recent studies have confirmed that the PVAAS projections (even as far as 3 years into the future) are more reliable at looking at the future performance of a student than the most recent PSSA score. Fall 2012 32 WB P. 12

33 How often did students with PVAAS probabilities of 70% or higher score at proficient or advanced? 33 WB P. 12 Fall 2012 A document containing more information can be found on the PVAAS Login Page.

34 Setting Goals and Raising Expectations 34 Using PVAAS projections (along with other data) to set the appropriate goals for all students Fall 2012

35 Projection Summary Reports What are they? This is a report that summarizes the numbers and percentages of students in various likelihood ranges of performing at a proficient level or higher on a future PSSA exam. Cautions This report provides ONE indicator about likelihood of future performance. Additional data should be used with the projection for better decision-making. WB P. 13 Fall 2012 35

36 District/School (Single Grade) Projection Summary Report WB P. 13 Fall 2012 36 Use the Projection tab in the blue menu bar to select projections to different grade levels and subjects.

44 Measuring Growth or Progress Students don’t all start the year at the same place academically Fall 2012 44

45 Measuring Growth or Progress Standard for PA Academic Growth Regardless of their entering achievement level, students should not lose ground academically Is it not a reasonable goal to maintain the achievement level of a group of students? Not necessarily increase their achievement level, but maintain their achievement level Fall 2012 45 WB P. 17

46 PVAAS Growth Measure & Color Descriptors The Growth Measure represents the amount of growth a group of students has made. The Growth Color Descriptors represent the level of evidence we have in the data to say whether or not the group of students increased, decreased, or maintained their achievement levels on average. PVAAS yields a Growth Measure AND a Growth Color Descriptor. Fall 2012 46 WB P. 18

47 PVAAS Value-Added Growth Descriptors Fall 2012 47 WB P. 18 DB 2 SEs or More Above 0 Significant evidence that the district/school exceeded the standard for PA Academic Growth LB 1 to 2 SEs Above 0 Moderate evidence that the district/school exceeded the standard for PA Academic Growth G Between 1 SE Above 0 & 1 SE Below 0 Evidence that the district/school met the standard for PA Academic Growth Y 1 to 2 SEs Below 0 Moderate evidence that the district/school did not meet the standard for PA Academic Growth R 2 SEs or More Below 0 Significant evidence that the district/school did not meet the standard for PA Academic Growth
